FASTENING FOR BRO-OCHES OR THE LIKE.

SPECIFICATION formingpart of Letters Patent No. 685,214, dated October 22, 1901. Application tiled January 9, 1900. vSerial No. 855. (No model) T0 a/ZZ whom, t may concern:

Be it known that I, ADoLPH F. E. LUTHY, a citizen of the UnitedStates, residing inthe city, county, and State of New York, have invented certain new and useful Improvements in Fastenings for Brooches or the Lilie, of which the following is a specification. f Y

This invention relates to fastcnings, and aims to provide certain improvementsparticularly applicable for jewelryV-fastenings.

Heretofore in fastenings for brooches various attempts .have been made to produce a safetyfastening for preventingaccidental or unauthorized ldisengagement of lthe pintongue from its holder or hook-piece. Such devices have generally operated on the principle of preventing escape of the tongue from the holder by means of an additionalmoving part which has been moved into the path of the pin-tongue for preventing its disengagement.

My invention aims to provide a fastening of this general character which shall be simple, cheap, strong, and compact and which can be relied on to effectively resist all ordinary causes of accidental orunauthorized unfastening.

To this end in carrying out the preferred form of my invention asapplied to a fastening for a brooch I provide an improved hookholder, an improved locking part, a screwthread for adjusting said parts, and certain other features of improvement, all of which will be hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side elevation of a brooch-frame provided with my improved fastening. Fig. 2 is an enlarged fragmentary side elevation thereof, showing the fastening in the open position. Fig. 3 is a similar view, partly in vertical axial section, showing the fastening in the locking position. Fig. 4 is a side elevation of the lock alone, and Fig. 5 is a fragmentary cross-section cnt on the line 5 5 of Fig. 3.

Referring to the drawings, let A indicate the frame of `a brooch or other article; B, the hinge-post; C, the pin; D, its hinge-axis; E, its tongue; F, the hook-post or holder, and G its notch. These parts may be of any usual or suitable construction which will permit springing of the pin inwardly until it is opt-he notch, as indicated in dotted lines in Fig. 2.

According to the preferred forni of my in-4 vention I provide an improved locking part kI-I and improved means for manipulating and fastening it. The lock H-has a pin-cavity I, open at its inner end for receiving the pin, and a pin-notch J for permitting the pin to pass into and out of this cavity.'V The lock is adjustably connected to the holder F, preferably so as to be movable rotatively therein and axially thereof. Asshown, a screw is provided for adjusting the lock'axially of the holder. Preferably the lock is formed of a small metal tube a., having a' fixed inner head or collar b at one end and a fixed handle or gnarled cap-nut c at its other end. The tube alias an external screw-thread d cut onv it from end to end, and the notch J is cut through the tube and its collar h. The holder is preferably formed ofatube @,connected bya basef to the frame A and provided with an d of the lock. Atits inner and'outer ends inner face being opposite the facej of the collar b and the outer face being opposite the face la of the handle c. These faces are so proportioned that when the faces h and jcorne together as the lock is unscrewed they will arrest unscrewing of the lock at the time that the notches J in the lock and G in the holder coincide. These notches are of such relative size and length that when they coincide in the open position of the lock their inner en ds will be outwardly of the end of the pin-tongue, soV that the latter can be sprung inwardly and laterally for passing into or ont of the fastened position. They are also so proportioned that when the lock is screwed to the locked position the notch in the lock will have passed inwardly 'of the pin-tongue of the pin to such extent that it will be impossible to remove the pin while the lock is locked, as best seen in Fig. l. In the locked position the faces and 7c abut with sufficient intimacy to resist any ordinary tendency to unscrewing, and in the unlocked position the faces 7i and j have the same effect, so that when the lock is set tight internal screw-thread g, engaging the thread posite vrthe notch G and then laterally ont of I the tube e is formed with faces t and il, the

ICO

- fastened with ordinary facility, and when or unconscious separation of the lock and in citherof these two positions it will be mainE tained in the position in which it is set until sulicient force is applied to it to free it, the force necessary being such that it could not be applied accidentally or surreptitiously without being noticeable to the wearer. The collar b is preferably screwed on the tube a with a tight fit, and the handle c is preferably a gnarled cap-nut `screwed on the end of the tube and'closing it. The collar is of the same diameter as the tube e, and the upper side of its notch is beveled at Z similarly to the bevel m on the tube.

In use the lock will be screwed to one position or the other for opening or closing. When open, the pin can be fastened and unlocked the pin cannot be released except by special manipulation.

It will be seen that my invention provides improvements which can be readily and advantageously availed of, and it will be understood that the invention is not limited to the exact details of construction, arrangement, and combination set forth' as constituting the preferred form of my invention, since it can be employed in whole or in part according to such modifications as circumstances or the judgment of those skilled in the art may dictate without departing from the spirit of the invention.

It will be seen that the lock H is not only a fastener for the pin-tongue but is also a point-protector therefor, inclosing the point of the pin in its pin-socket and effectively guarding against injury to the user from contact with the pinpoint during all fastening positions of the fastener; also, that the collar b serves as a means for guarding against complete unscrewing of the lock from the holder, so that the possibility of accidental holder is avoided.

Vhat I claim is- 1. In fastenings for brooches and other articles, the combination with a holder having a notch for receivingapin-tongue, and apin,- tongue entering laterally into said holder through said notch, of a lock Within the holder and movable longitudinally of the axis thereof, having a notch coinciding With the notch in the holder, a socket for receiving the pintongue, and an unbroken cylindrical wall at rear of said notch surrounding said socket, said lock having'an external screw-thread, and said holder having an internal screwthread engaging that of the lock, and means for screwing the lock longitudinally of the axis of the holder for moving the lock toward and from the position at which said notches coincide, said lock being of such length relatively to the holder that it can be screwed along the pin-tongue to a position where its notch is beyond the holder, and the notch of the holder is closed by the cylindrical wall of the lock.

2. In fastenings for brooches and other articles, the combination with a frame A, pin C, and holder F, having an internal thread and a notch G, of a lock H consisting of a tube having an external thread screwing through the internal thread of the holder, a notch J coinciding with the notch in the holder, and an unbroken cylindrical Wall at rear of said notch, a collar b, and a handle c, said holder having faces h and z', and said lock having faces j and 7c, said faces abutting at the extreme positions of adjustment of the lock, for holding it in its open and locked positions respectively, and said faces ,7' and 7o being spaced apart such a distance that when the face 7c abuts against the face t' said notch J is beyond the holder, and the notch G is closed by said cylindrical wall.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
